ditto to what Roel said here. Luckily, with miracle of free internet telephone (Skype) I was able to call Tony directly and explain the situation as Roel described. Tony luckily was able to locate the Tyros power cord (right one afterall) and plug it directly into the Tyros. He mistakenly thought that he was missing the AC power adapter box that comes with the other PSR keyboards: PSR3000, PSR2000, etc.

Tony, happy music making. Please post your 'side by side' comparison of the PSR3000 & Tyros, in both their sound(s), styles, and features.
